all these trucks (even the same years) vary in some degree.you really didnt provide enuff info about your 4 inch lift. do you have rear springs or blocks ? drive shafts should be ok. you may have to get longer brake lines or at least relocate or disconnect the bracket mounts. you may also have to get some shims to correct pinion or drop t-case due to vibration, but this is not always the case. depending on your kit youll have to get a drop down steering arm. you may also run into some other steering problems depending on how well the former owner of your vehicle maintained it (lets hope better than mine did). are you also planning on upgrading the tires as well ? /forums/images/icons/confused.gif /forums/images/icons/tongue.gif /forums/images/icons/laugh.gif hope this helps. others may provide you with more info.
